Investigating how overnutrition affects fat tissue and insulin resistance

Short-term High-fat Overnutrition Induces Insulin Resistance in White Adipose Tissue

NA · German Diabetes Center · NCT06193668

This study is testing how a short-term high-fat diet affects fat tissue and insulin resistance in people to see if it leads to problems like type 2 diabetes.

What this trial studies

This study aims to explore the mechanisms behind insulin resistance in white adipose tissue (WAT) induced by short-term high-fat diet overnutrition. Participants will be randomly assigned to either a hypercaloric high-fat diet or a macronutrient-balanced diet for three weeks. The study will analyze differences in fatty acid and glucose metabolism between the two groups to better understand the impact of diet on insulin sensitivity. The findings could provide insights into the metabolic disturbances associated with type 2 diabetes.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18 to 40 with a BMI under 29 who do not engage in regular sports activities.

Not a fit: Patients with diabetes, chronic diseases, or those on medications affecting metabolism are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved dietary recommendations for preventing or managing insulin resistance and type 2 diabetes.

How similar studies have performed: Previous studies have shown promising results in understanding dietary impacts on insulin resistance, making this approach both relevant and potentially impactful.
